HULL FOR VESSELS.

Specification of Letters Patent. 1

Patented (wet. 2?, 19133.

Application filed September 5, 1912. Serial No. 718,640..

To all whom it may concern Be it known that I, PHILIP J. J. SAUPE, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, ha-ve,invented certain new and useful Improvements in Hulls for Vessels, of which the following is a specification.

My invention relates to hulls for Vessels.

The object of my invention is to so construct the hull of a vessel that as it is driven through the'water, thefront end of the vessel or hull will be lifted, thus causing less displacement of water than is ordinary in the normal construction of bulls.

My invention includes the formation of the forward extremity of the hull into a thin and what might be called knife edge, the same extending from a point beginning nearly at the height of the vertical bow and upon a gradual curve downwardly to a point at which the'turn of the body forms the bottom of the hull.

In practice, I may provide the stern of the boat with the same character of formation for the purpose of inducing the same character of lifting efi'ect in rearward motion of the vessel, but normally the structure is built upon the lines illustrated in Figure 2.

My invention also includes deflector wings or boards connected with the bow of the vessel, on the lines on either side of the bow conforming to the center of the concave or offset between the knife edge portion of the bow and the outwardly curved upper portion thereof.

My invention also includes the shaping of the bottom of the vessel into a: general 0blong oval shape best illustrated in Fig. 2, which terminates at its forward end immediately underneath the bow into a gradually narrowing point and extending rbarwardly, a gradually increasing swell to a point at about the longitudinal center of the hull and then gradually decreases toward the stern.

My invention also includes a propeller specially adapted for use in connection wlth the vessel hull or body disclosed.

Referring to the drawings, Fig. 1 1s a top view of my device; Fig. 2 is a side elevation of the same; Fig. 3 is atop view of a modified form of the hull; Fig. 4 is similarly a side elevation of a modified form of the hull; Fig. 5 is a bow end view of the vessel b v; Figs. 6 and 7 are respectively front and side views of a propeller; Figs. 8, 9 and- 10 are the same as Figs. 5, 6 and 7.

In the drawings, 2 is the vessel body, which is designed to be expanded to substantially its greatest width at its center, and for a considerable distance therefrom toward its respective ends. The bull or body of the vessel is generally formed on about normal lines except that at the forward or bow end of the vessel, a distinct and positive narrowing of the prow is accomplished by a sharp inturn, as at 3, upon a gradual downward curved line from the front and upper portion of the proW and rearwardly substantially to the bottom or to the most positive intu'rn. of the bottom. My ideas are correctly expressed and shown in Fig. 2. The inturn 3 is made as positive as possible and as quickly as may be, in forming metal, to bring it into the form of a knife edge as 4, which knife edge form continues as shown in Fig. 2, from the forward end of the bow to the offset or curved trough formation in the bow. I may, in practice,

supplement the offset of the metal by adding the deflector boards as 5 on either side of the prow. The lower body is formed on the general curved line as shown at 6, which form continues forwardly tapering to a point as at 7 andat the rear as at 8, the shape of the bottom being substantially that of one half of a "cigar of normal shape. A keel of any sort may be formed as a part of the boat body. but as my invention has nothing to do with the keel, it have not shown same herein.

In carrying out my invention, I may form the rear end of the vessel upon lines disclosed in Fig. 4, substantially or exactly conforming to the shape of the prow of the vessel so as to serve the same lifting function in rearward movement of the hull as in its forward movement.

lln the construction illustrated, and in carrying out my invention, the purpose and intent is that it shall be applied in the mannor disclosed to provide an abrupt battle at the forward end of the vessel body that when applied to vessels which ordinarily attain great speed in travel, the front end of the hull will be positively raised out of the water so that it will be substantially clear therefrom and so that the central portion of the vessel will ride substantially upon the surface of thewater with the rear only the inturn battle were depended upon,

and hence its application thereby broadened to vessels of slower normal speed.

In Figs. 6 and 7 I have disclosed a pro-- peller specially designed for use in connection with the hull of my particular design. The propeller is of the leaf or wing type that is commonly in use but distinguishes therefrom markedly in the angle or disposition of the wings or propeller blades. The propeller has the normal and usual relatively angular disposition, but my propeller in addition, is provided with the abrupt inturn as at 10 best shown in Fig. 7, which has the effect in practice of supplementing the pushing effect of propeller blades set at the normal angles relatively and of-presenting additional resisting or pushing faces acting upon the principle of a boat sail, as the gradual incline extends and increases the resistance or pushing In the use of my propeller, a greater amount of power is required to revolve, as there is a greater resistance, but the speed is materially increased, and as power is practically unlimited in connection with vessels, and as speed is the essential of my invention, I have provided a special form of propeller, and great speed may be attained at the expense of power.

In Fig. 2 of the drawings,I have, shown roe see? a single screw or propeller, but in Fig. 4: I have also shown a double propeller and how the same may be positioned with relation to 'the hull, if formed as shown in said figure.

I have herein shown two forms of embodiment of my invention and they. correctly represent the principle of its application, but I do not desire to be confined to the exact structural lines disclosed, but that the principle may be carried out within reasonable limitations and still fall within the scope of my invention;

What I claim is:

1. A vessel hull formed at the prow into a substantial knife edge extending and comprehending the portion of the prow beginning at its forward and uppermost part and extendingrearwardly and downwardly on a gradual curved line to substantially the bot tom of the hull in advance of the widest portion thereof as shown, and an out-turned portion along the full length line above described to form an abrupt battle ofiset substantially; as described and shown.

2. A vessel hull formed at the prow into a substantial knife edge extending and com prehending the portion. of the prow beginning at its forward and uppermost part and extending on a gradual curved line to substantially the bottom of the hull, an abrupt out-turn along the full line above described to form an abrupt offset, and a battle board on either side of the prow and positioned along the depressed line and at the beginning of the upturned part, substantially as described.

In testimony whereof I have afiixed my signature in presence of two witnesses.
